Update.
2004-03-06 Ulrich Drepper <drepper@redhat.com> * elf/dl-open.c: No need to pass any parameter to _dl_start_profile. They are the same in both places. * elf/dl-profile.c: Likewise. * elf/rtld.c: Likewise. * sysdeps/generic/ldsodefs.h: Likewise. * elf/dl-support.c: Define _dl_profile_output variable. Initialize it.
